Steve Jobs took a shot at Google yesterday, when he suggested in his Big Event presentation that Google's spectacular Android activation numbers were exaggerated.

Some of our friends, Steve said--obviously referring to Google, which is anything but a friend--include upgrades in their activation numbers. But Apple doesn't. And the iPhone OS is seeing 230,000 activations a day.

Well, now Google has responded, telling Fortune's Seth Weintraub that it doesn't include upgrades in its activation numbers, either (200,000 a day as of August, and growing fast). What's more, Google says, its activation numbers may be understated because they only include phones that use Google services.

And here's Google's response: “The Android activation numbers do not include upgrades and are, in fact, only a portion of the Android devices in the market since we only include devices that have Google services.”
